Vegetable Oil SVO WVO waste cooking oil as biofuel

[Jake Palmer]

I've got a 1987 Sammy with a VW turbo diesel.

I bought it for $400, with the intention of whipping it like a red-headed stepchild. Scored a used ACME adapter kit and performed a dieselfication last fall.

The veggie setup is pretty basic: small 20 liter tank, heated fuel pickup, HoH, homemade heat exchanger and a Pollak 6 port valve. For instrumentation, I have a vacuum guage and an indicator light that's on when I'm on vegetable oil. I've got about 20k kms on vegetable oil with it.

This thing is a daily driver. I just love it, best money I ever misspent. The 1.6TD is great in this thing, goes like nuts. Have a 1.9aaz with k24 going in when I do the clutch in a month or so.


I'll post some pics of the veggie conversion later. Consider yourself forewarned though, it ain't pretty!

The veggie tank: On the top, you can see fuel and coolant lines going into the heated fuel pickup. You can also see the insulated Hose on Hose (HoH) running towards the front of the car.


You can see the HoH going up the driver's side footwell, where it passes through the firewall. You can also see the vacuum gauge in the center of the dash. It reads the vacuum in the fuel line just before the injection pump, so I can see if the diesel or veggie filter are plugging:



The fuel & coolant lines pass through the firewall where they connect to the wacky, inefficient copper heat exchanger. The fuel passes through the center, then out on the left, through the small filter and into the 6 port valve.



Here's another look at the (messy) engine compartment. A couple things worth noting:
-glow plugs have individual wires run instead of the standard "bus bar". This makes identifying dead plugs MUCH easier.
-I used cheapie "worm gear" hose clamps instead of the better fuel injection hose clamps... something I generally advise against.


I have a really nice 1.9 AAZ turbodiesel that I'll swap in this summer. At the same time, I'll clean up the wiring & plumbing, add a FPHE & vegtherm, and probably even paint it.

Sweet set up. Let me know if you ever want to sell it. I miss having a little 4x4 since selling my TJ

Thanks for the compliment!

The only way I'll ever get rid of Sammy is if it gets hit by lightning or run over by a bulldozer. I just love it.

love the heat exchanger, needs a little Neo-wrap, I'll include if you'll measure. PM please.

Thanks jeff, but I'm about to disconnect the heat exchanger altogether and start running cold veg. Doing some destructive testing!

After that I'll be putting in a 1.9AAZ vw diesel. I'll have a vegtherm & 16 plate FPHE. You ought to work on a FPHE cozy! You'd sell lots of them!

There are thousands of unprotected FPHE's. Big market, Jeff.
Since I started to sell my Insulation Box everybody wants them.

OR you could recycle some high-density foam (Free) and wrap your flat plate heat exchanger… helps with the metal to metal vibration …
